An Error Sensitivity Model for Doppler Positioning Using Transit Satellites

Abstract

The Transit satellite positioning system is a commonly used navigation aid included in the Marine Integrated Navigation System (MINS-B II) and Primary Land Arctic Navigation System (PLANS). MINS and PLANS are both kalman filter based multi-sensor optimally integrated navigation systems and as such require detailed stochastic and deterministic error models for all of their sensors (to form the Kalman filter measurement error sensitivity matrices). This paper provides a detailed geometric derivation of the deterministic error model relating the position error of a Transit satellite Doppler position fix (or similarly a SARSAT fix) to the error in the velocity and height that is fed into the Transit receiver (or assumed for the SARSAT transponder). This error model is presented in the form of explicit functions of variables which are normally provided by a Transit receiver with each position fix, namely the satellite maximum elevation angle, the satellite direction of travel and the receiver latitude. For generality the satellite orbital parameters are left in the expressions. Canada. (jhd)
